A Great Emperor in His Twilight Years: Invincible from the Moment I Enter the Primordial World

[Invincible protagonist + Great Emperor + Primordial World + Fantasy + Harem + Mythic Great Overarching Luo]

Su Bai transmigrates into a world much like Shrouding the Heavens.

He achieves the Great Emperor's Dao smoothly, and in his twilight years, plans to take a Forbidden Zone Supreme down with him before he dies.

Then he unexpectedly enters the Primordial World and lives a second life.

“As long as I don't die, you lot are the ones who will!” Su Bai snarls as he raises his butcher's knife against the Forbidden Zone Supremes.

He cuts his way from Beidou to the source of darkness, only to realize that he has become invincible.
